ata: libata-core: Allow command duration limits detection for ACS-4 drives
Even though the command duration limits (CDL) feature was first added in ACS-5 (major version 12), there are some ACS-4 (major version 11) drives that implement CDL as well. IDENTIFY_DEVICE, SUPPORTED_CAPABILITIES, and CURRENT_SETTINGS log pages are mandatory in the ACS-4 standard so it should be safe to read these log pages on older drives implementing the ACS-4 standard. Fixes: 62e4a60e0cdb ("scsi: ata: libata: Detect support for command duration limits") Cc: stable@vger.kernel.org Signed-off-by: Igor Pylypiv <ipylypiv@google.com> Signed-off-by: Damien Le Moal <dlemoal@kernel.org>
